I think it depends also partly on the question. If it's a formal question, or a hard science question, with a precise, provable answer, disclaimer would be good, and acceptance of downvotes if other's deem it incorrect. (OK to remove also.)
For fuzzy questions, which I often answer a lot of on other stacks, I'll directly say "this is my guess" before I make a supportable, well reasoned argument, because there is no source that has answered it, or there may even be differences of opinion.
("What is the difference between a sword and a knife" on martial arts, as an example. I've never been able to find an answer, but now that I've studied them sufficiently, significantly more than most people, I'm confident I can answer it, and the correctness of that answer will be validated by the argument.)
The humanities stacks, such as Literature, don't often have objective answers, and are more about providing analysis which may benefit students and scholars. Sometimes an OP will accept the one they most agree with, but, in those cases, all well reasoned answers are valuable.
We have some fuzziness in the case of philosophy and social aspects, but those questions are more rare here.
